Glendale, CA PSI Services LLC (PSI), a global workforce assessment and management solutions provider to corporations, federal and state government agencies, professional associations, certifying bodies, and leading academic institutions, today announced that it has acquired the pre-employment testing assets of Development Dimensions International, Inc., a human resources and leadership development consultancy and front-runner in leadership selection, development, and succession planning

PSI will acquire DDI’s automated pre-employment testing content, including customizable career batteries and adaptive reasoning tests, adding to PSI’s suite of talent measurement solutions for healthcare, manufacturing, sales, professional individual contributors, support services, and customer service

“PSI’s history of designing and delivering valid assessments using the latest technologies has ensured we have stayed at the forefront of the workforce assessment space for over 70 years. The addition of DDI’s non-leadership assessment solutions to the PSI True Talent™ platform further enhances our standing as the leading provider of workforce assessment content delivered through cutting edge technology,” said Steve Tapp, CEO of PSI

As PSI Services expands its PSI True Talent™ technology offering into AI-driven digital interviewing and in-application virtual experiences, DDI’s manufacturing and production simulations together with their computer adaptive reasoning tests will further bolster PSI’s solutions in the talent measurement space

“Over the course of nearly five decades, DDI has built a strong reputation on the quality and accuracy of our assessment services, and we’ve seen a growing demand from companies that want to use our assessments to bring more objectivity into their hiring and promotion decisions,” said Tacy Byham, CEO of DDI. “As the market has grown, we made the decision to focus our core business exclusively on serving leaders. Because PSI is one of the most reputable testing companies in the world, we believe that they are the right company to acquire our testing services for non-leadership roles and continue our legacy of providing top-tier service and innovation to our clients.”
